Description
Technical field
The present invention relates to the environmental chemical engineering field, relate in particular to the agent of a kind of ammonia nitrogen waste water pre-treatment reduction reaction.
Background technology
Ammonia nitrogen in the waste water is the important substance of body eutrophication and environmental pollution; Any discharging unprocessed or that handle incomplete nitrogen-containing pollutant can cause a large amount of breedings of algae and other mikrobes in the water; Thereby water quality is constantly worsened, can make oxygen in water descend the water ecology dysequilibrium when serious; Fish kill quickens the lake and wears out.Ammonia nitrogen can cause the tap water peculiar smell, increases the waterworks operating load; Increase the chlorine consumption in water disinfection and the industrial cycle germicidal treatment process; In the industrial application, to some metal, particularly copper has corrodibility; During reusing sewage, ammonia nitrogen can impel the breeding of mikrobe in conduit and the watering equipment in the reuse water, forms biofouling, blocking pipe and watering equipment, and influence heat exchange efficiency.In the water body, ammonia is oxidized to nitrate salt and nitrite under the effect of nitrifier and nitrococcus, and nitrate salt can bring out baby's methemoglobinemia by tap water, and the NSC 223080 that generates after the nitrite hydrolysis has strong carinogenicity, the direct threats human health.
The waste water that ammonia nitrogen waste water mainly discharges from industry production such as petrochemical industry, coking, pharmacy, process hides, chemical fertilizer, feed, breed, meat processings, and sanitary wastewater, sludge digestion liquid and rubbish infiltration filtrating etc." ammonia synthesizing industry pollution discharge standard " stipulates that (GB13458-2001) medium-sized enterprise's ammonia nitrogen emission concentration is less than 70mg/L; Stipulate that the trade effluent ammonia nitrogen concentration should be less than 25mg/L in the highest permission emission concentration of national sewage comprehensive emission standard second pollutant; But wastewater regenerating and recycling stipulates (HG/T3923-2007) that according to " recirculated cooling water reuse water water quality standard " ammonia nitrogen concentration should be in the 1-3mg/L scope.
Allow the raising of emission standard along with ammonia nitrogen; The ammonia nitrogen waste water treatment process is also had higher requirement; Ammonia nitrogen waste water treatment method is mainly chemical precipitation method at present; Promptly compound and phosphoric acid or the hydrophosphate through in waste water, adding magnesium generates magnesium ammonium phosphate sediment, thereby removes the ammonia nitrogen in the waste water.But mainly there is following problem in this method: the microorganism active that processing cost is high, the process for producing high salinity can influence subsequent biological treatment; And this process need independent control pH value, its process is complicated, loaded down with trivial details, has hindered the application of this method in reality.
Summary of the invention
The purpose of this invention is to provide the agent of a kind of ammonia nitrogen waste water pre-treatment reduction reaction,, can not improve the water body saltiness, can not reduce the water body biodegradability, cause disadvantageous effect can for follow-up biochemical reaction the water body non-secondary pollution.
The objective of the invention is to realize through following technical scheme:
A kind of ammonia nitrogen waste water pre-treatment reduction reaction of the present invention agent is mixed and made into by following raw materials by weight percent: Poly aluminum Chloride (PAC) 40, poly-ferric chloride 40, SEPIGEL 305 15, Natural manganese dioxide 1, lithium 1, vanadium 1, silicon 2.
Said Poly aluminum Chloride (PAC) is Powdered, granularity φ 0.3～0.5mm; It is Powdered that poly-ferric chloride is, granularity φ 0.9～1.5mm; It is Powdered that SEPIGEL 305 is, granularity φ 0.02～0.05mm; It is Powdered that Natural manganese dioxide is, granularity φ 0.2～0.5mm; It is Powdered that lithium is, granularity φ 0.2～0.5mm; It is Powdered that vanadium is, granularity φ 0.2～0.5mm; It is Powdered that silicon is, granularity φ 0.2～0.5mm, and the purity of above-mentioned each raw material is all greater than 95%.
The making method of above-mentioned ammonia nitrogen waste water pre-treatment reduction reaction agent may further comprise the steps:
1) takes by weighing each raw material according to each raw material weight per-cent;
It is even that the lithium powder that 2) will take by weighing, vanadium powder end, Si powder and magnesium oxide powder are put into the container thorough mixing;
Mix in the SEPIGEL 305 powder adding container that 3) will take by weighing;
Mix in poly-ferric chloride powder that 4) will take by weighing and the Poly aluminum Chloride (PAC) powder adding container;
5) with all raw materials mix evenly after, be to add purity 99% zero(ppm) water at 1: 25 according to weight ratio, mix also and stir, about 120 rev/mins of mixing speed stirs to seal to deposit after 10 minutes and gets final product.
The present invention has the following advantages: consumption is less, and it is obvious that water body removes ammonia nitrogen; To the water body non-secondary pollution, can not improve the water body saltiness, can not reduce the water body biodegradability, cause disadvantageous effect can for follow-up biochemical reaction; Adopt waste water of the present invention, obviously exceed about 40%～45% degradation rate, and under original low concentration condition, still keep the degradation rate more than 85%.
Embodiment
The agent of the described ammonia nitrogen waste water pre-treatment of embodiment of the invention reduction reaction is by following raw material (unit: kilogram) be mixed and made into: Poly aluminum Chloride (PAC) 40, poly-ferric chloride 40, SEPIGEL 305 15, Natural manganese dioxide 1, lithium 1, vanadium 1, silicon 2.Said Poly aluminum Chloride (PAC) is Powdered, granularity φ 0.3～0.5mm; It is Powdered that poly-ferric chloride is, granularity φ 0.9～1.5mm; It is Powdered that SEPIGEL 305 is, granularity φ 0.02～0.05mm; It is Powdered that Natural manganese dioxide is, granularity φ 0.2～0.5mm; It is Powdered that lithium is, granularity φ 0.2～0.5mm; It is Powdered that vanadium is, granularity φ 0.2～0.5mm; It is Powdered that silicon is, granularity φ 0.2～0.5mm, and the purity of above-mentioned each raw material is all greater than 95%.
The making method of above-mentioned ammonia nitrogen waste water pre-treatment reduction reaction agent may further comprise the steps:

When taking according to medicament: waste water=ratio added in 1: 1000.Waste water finally is converted into N through chemical reaction repeatedly
2And NH
3Process in, can the organic amino saturation concentration before and after the degree of waste water and reaction reaction of the present invention and the reaction in the water body have determined directly and the Ammonia material in the waste water has been removed thoroughly that reagent is that step of reaction provides good catalytic oxidation-reduction effect.
Use ammonia nitrogen waste water pre-treatment reduction reaction of the present invention agent and do not use the contrast of the degradation rate of ammonia nitrogen waste water pre-treatment reduction reaction of the present invention agent to see table 1:
Table 1
Can obviously find out from above-mentioned contrast multi-group data; Do not use the wastewater treatment degradation rate of the efficient reduction reaction agent of ammonia nitrogen waste water pre-treatment lower; Processing efficiency descends its degradation rate gradually along with the decline of former water ammonia nitrogen concentration initial value; And the waste water of the efficient reductive agent of employing ammonia nitrogen waste water pre-treatment, its degradation rate obviously exceeds about 40%～45% degradation rate, and under original low concentration condition, still keeps the degradation rate more than 85%.
Instance:
Certain paper mill, 5000 tons/day of day generation waste water.NH in its water body
3-N (ammonia nitrogen), P (phosphorus) exceeds standard, because this plant is outmoded, and plan to implement to move in two years, so manufacturer is unwilling to carry out the large-scale equipment invest in the transformation of real estate; To customer demand, specially adopt reagent of the present invention, in water body, add the waste water NH after flocculation treatment according to 1 ‰～1.5 ‰ ratios
3-N and P content reach national grade one discharge standard, get permission discharging.
